IMPROVEMENT lN SPRING-HINGES. I

Specification forming part of Letters Patent No. 167, l 14., datedAugust 24, 1875; application filed June 26, 1875.

To all whom it may concern Be it known that I, RICHARD M. C. PARKER,

of Memphis, in the county of Shelby and State of Tennessee, haveinvented a new and valuable Improvement in Hinges; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure l of the drawings is a representa tion of a plan view of myhinge. Fig. 2 is a vertical sectional view of the same, and Fig. 3 is adetail view thereof.

This invention has relation to certain im provements .in hinges; and itconsists in the construction and novel arrangement of the oil-cup andits transverse bearing for the lower end of the journal, the hollowcup-plate, the upper end of the same, the spindle-leaf, and the springand its bearings, all as hereinafter fully shown and described.

In the accompanying drawings, the letters A A indicate the leaves of myhinge, each of which is provided with suitable screw-holes, The leaf Ais recessed at its upper end, as shown at b, for the reception of thecapplate 0, which is also provided with screwholes corresponding tothose in the upper end of the plate A. The cap B is formed on theprojecting end of the plate, and is in the form of an inverted hollowsocket, the exterior being finished in conical or other ornamental form.On the lower end of the leaf A is formed a socket, O, projectingsomewhat obliquely, so as to be above the level of the leaf. This socketis of suflicient depth to hold a quantity of oil, and within it is casta transverse bar or bearing, d, upon which the lower end of the spindleor journal-bar rests, theupper end of the same being received into thehollow of the cap B. On the leaf A is cast the oblique lug D, from.which extend upward and downward the spindle arms or journals 6 e, whichbear, as above stated, in the oilsocket and cap, respectively. The arm eis plied is closed. The spring is kept on the arm of the journal by thecap, in which said journal has its bearing.

WhatI claim as new, and desire to secure by Letters Patent, is-

l. A hinge-leaf having an oil-socket, O, and within the same thetransverse bearing d, cast with said leaf and socket, substantially asspecified.

2. The combination, with the leaves A A, removable cap B, andspindle-arm e, of the spring 8 and its spread arms h It, bearing inrecesses m in said leaves, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
